Roadside Emergencies

If you do not use the proper fuel filler cap, excessive pressure or
vacuum in the fuel tank may damage the fuel system or cause
the fuel cap to disengage in a collision, which may result in possible
personal injury.
Automotive fuels can cause serious injury or death if misused or
mishandled.
Gasoline may contain benzene, which is a cancer-causing agent.
Observe the following guidelines when handling automotive fuel:
•Extinguish all smoking materials
and any open flames before
refueling your vehicle.
•Always turn off the vehicle before
refueling.
•Automotive fuels can be harmful
or fatal if swallowed. Fuel such as gasoline is highly toxic and if
swallowed can cause death or permanent injury. If fuel is swallowed,
call a physician immediately, even if no symptoms are immediately
apparent. The toxic effects of fuel may not be visible for hours.
•Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind
can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.
•Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.
•Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.

Fuel filler cap
Your fuel tank filler cap has an indexed design with a 1/4 turn on/off feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise until it stops.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the
filler pipe.
5. Turn the filler cap clockwise until it clicks.
If the “Check Fuel Cap” indicator comes on and stays on after you start
the engine, the fuel filler cap may not be properly installed. Turn off the
engine, remove the fuel filler cap, align the cap properly and reinstall it.
If you must replace the fuel filler cap, replace it with a fuel filler
cap that is designed for your vehicle. The customer warranty may
be void for any damage to the fuel tank or fuel system if the
correct genuine Ford or Motorcraft fuel filler cap is not used.
The fuel system may be under pressure. If the fuel filler cap is
venting vapor or if you hear a hissing sound, wait until it stops
before completely removing the fuel filler cap. Otherwise, fuel may
spray out and injure you or others.
If you do not use the proper fuel filler cap, excessive pressure or
vacuum in the fuel tank may damage the fuel system or cause
the fuel cap to disengage in a collision, which may result in possible
personal injury.
